Solution

The correct option is B Allergic infection
  • A skin prick test, also called a puncture or scratch test, checks for immediate allergic reactions to approximately 40 different substances at once.
  • This test checks for a skin reaction to common allergy provoking substances, such as foods, moulds, dust, plants, or animal proteins.
  • If your skin reacts to a substance, chances are that you are allergic to it.

So, the correct answer is option C.
